3.Machine Structure and Working Theory

 

The structure and working theory of PZ-5 concrete spraying machine is shown as figure 1. The premixed materials are filled into vibrating hopper 1, and then passing through vibrating sieve to hopper 3. From there it flows into the through-going chambers of rotor 7 by the action of agitator 2 and moves to the discharge outlet with rotor running, where it is blown to Vortex Stream Implement 10 by compressed air leaded by air pipe 14. Here it is blown by scattering, accelerating, whirling, and floating vortex stream and through conveying hose to the nozzle, where a little adjustable amount water (for damp-mix shotcreting) is added.

 

PZ-5 concrete spraying machine mainly includes drive device, rotor assy., air conveying system, spraying system and electric control casing etc.
